IntroductionRead this manual thoroughly before operating orservicing this unit.

Warnings, Cautions, and NoticesSafety advisories appear throughout this manual asrequired. Your personal safety and the properoperation of this machine depend upon the strictobservance of these precautions.

The three types of advisories are defined as follows:

WARNINGIndicates a potentially hazardous situationwhich, if not avoided, could result in death orserious injury.

CAUTIONIndicates a potentially hazardous situationwhich, if not avoided, could result in minor ormoderate injury. It could also be used to alertagainst unsafe practices.

NOTICEIndicates a situation that could result inequipment or property-damage onlyaccidents.

Important Environmental ConcernsScientific research has shown that certain man-madechemicals can affect the earth’s naturally occurringstratospheric ozone layer when released to theatmosphere. In particular, several of the identifiedchemicals that may affect the ozone layer arerefrigerants that contain Chlorine, Fluorine and Carbon(CFCs) and those containing Hydrogen, Chlorine,Fluorine and Carbon (HCFCs). Not all refrigerantscontaining these compounds have the same potentialimpact to the environment. Trane advocates theresponsible handling of all refrigerants-includingindustry replacements for CFCs and HCFCs such assaturated or unsaturated HFCs and HCFCs.

Important Responsible RefrigerantPracticesTrane believes that responsible refrigerant practicesare important to the environment, our customers, andthe air conditioning industry. All technicians whohandle refrigerants must be certified according to localrules. For the USA, the Federal Clean Air Act (Section608) sets forth the requirements for handling,reclaiming, recovering and recycling of certainrefrigerants and the equipment that is used in theseservice procedures. In addition, some states ormunicipalities may have additional requirements thatmust also be adhered to for responsible managementof refrigerants. Know the applicable laws and followthem.

SSA-SVX06J-EN 7

Pre-InstallationThe final position for the air handler must be dictatedby required service access to it, weight distributionover structural supports, and by the locations ofelectrical, refrigerant and condensate drainageconnections. After this is determined, the followingpreparations should be made.

Unit InspectionInspect material carefully for any shipping damage. Ifdamaged, it must be reported to, and claims madeagainst the transportation company. Compare theinformation that appears on the unit nameplate withordering and submittal data to ensure the proper unitwas shipped. Available power supply must becompatible with electrical characteristics specified oncomponent nameplates. Replace damaged parts withauthorized parts only.

IImmppoorrttaanntt:: Units ordered with a VFD cannot be fieldconverted to 460 V from 208-230 or from208-230 V to 460 V.

Inspection ChecklistTo protect against loss due to damage incurred intransit, complete the following checklist upon receipt ofthe unit.

☐ Inspect individual pieces of the shipment beforeaccepting the unit. Check for obvious damage to theunit or packing material.

☐ Inspect the unit for concealed damage before it isstored and as soon as possible after delivery.Concealed damage must be reported within 15days. If concealed damage is discovered, stopunpacking the shipment. Do not remove damagedmaterial from the receiving location. Take photos ofthe damage if possible. The owner must providereasonable evidence that the damage did not occurafter delivery.

☐ Notify the carrier’s terminal of damage immediatelyby phone and by mail. Request an immediate jointinspection of the damage by the carrier and theconsignee.

☐ Notify the sales representative and arrange forrepair. Do not repair the unit until the damage isinspected by the carrier’s representative.

Testing for LeaksAll TWE units are shipped with a holding charge ofnitrogen in each circuit and should be leak testedbefore installation.

1. Remove the access panel.

2. Locate the liquid line or suction line access valve foreach circuit.

3. Install gauges to determine if the circuits are stillpressurized. If not, the charge has escaped andshould be repaired as required to obtain a leak-freecircuit.

Before preparing the unit for lifting, estimate theapproximate center of gravity for lifting safety. Becauseof placement of internal components, the unit weightmay be unevenly distributed. See “Weights,” p. 21 forapproximate unit weights.

The crated unit can be moved using a forklift of suitablecapacity. For lifting the unit into an elevated mountingposition, run lifting straps or slings under the unit andattach securely to the lifting device.

Repositioning Drain PanAir handlers come with one drain pan that can beinstalled in any one of four positions; this allows forvertical or horizontal application and right or leftcondensate line connection.

NNoottee:: Important! All air handlers are shipped with thedrain pan installed in the horizontal position andthe connection on the left side (as shown inFigure 1, p. 8. If an alternate position is required,the drain pan should be repositioned beforesetting the air handler. Ensure there is enoughclearance to the sides of the unit forrepositioning the drain pan after installation.

1. Remove the access plate at the opposite end of thedrain connection. This plate secures and lifts theback end of the drain pan for sloping. It must beremoved before the drain pan can be removed. This

• Available power supply must agree with electricaldata on component nameplate.

• Some constant volume air handlers are shippedwired for 208-230 volt applications and can beconverted for 460 volt by rewiring the blowermotor. (This includes models TWE07243B,TWE09043A, TWE09043B, TWE12043A,TWE12043B, TWE15043B and TWE18043B).

Converting Motor to 460 VoltIImmppoorrttaanntt:: Units ordered with a VFD cannot be field

converted to 460 V from 208-230 or from208-230 V to 460 V.

1. Ensure power is disconnected to unit by followingthe warning above.

2. Remove unit access panels closest to motor.

3. Open terminal cover on lead end of motor.

4. Pull voltage selector plug from low voltageselection (see Figure 3, p. 9).

5. Shift the plug (or rotate 180°) to align plug for high

voltage selection and re-insert plug.

IImmppoorrttaanntt:: When re-inserting voltage selectionplug, ensure it is fully seated.

6. Replace terminal cover on lead end of motor.

7. Replace unit access panels.

Refrigerant PipingReorienting Evaporator Coil (TWE126/150 and 156/180)IImmppoorrttaanntt:: Applies to TWE126/150 and 156/180 when

positioned for vertical upflow. Unit isshipped in the horizontal position. Ifinstalling in the vveerrttiiccaall ppoossiittiioonn, the coilmmuusstt bbee reoriented by rotating the coil 4degrees (control box side) from theshipped position.

1. Remove screws from top evaporator coil bracket(bracket that attaches coil to cabinet and runs thelength of the unit). See Figure 4, p. 10.

2. Rotate evaporator coil approximately 4 degreesclockwise - looking from the control box end. Whenthe evaporator coil is rotated, the lower set ofevaporator coil bracket holes will align with thesupport bracket (from which it was originallyfastened).

3. Reinsert screws in evaporator coil bracket.

The air handler is designed so that refrigerant pipingcan enter from either the right or left hand side. It isshipped with the intent that the refrigerant lines willenter from the left hand side. To convert to right handentry, unbraze the elbow on the suction line and rotate180° and rebraze.

IImmppoorrttaanntt:: Access to refrigerant lines is limited in allhorizontal and some vertical applications.Therefore, refrigerant lines should bestubbed out and temporarily capped priorto setting the air handler. Protect adjacentsurfaces from heat damage when brazingin and around the air handler. See , p. 12.

The general location of the air handler is normallyselected by the architect, contractor and/or buyer. Forproper installation, the following items must beconsidered:

• Available power supply must agree with electricaldata on component nameplate.

NNoottee:: Unit voltage cannot be changed on unitsordered with a VFD.

• If external accessories are installed on the unit,additional clearances must be provided.

• All duct work should be properly insulated toprevent condensation and heat loss.

• Refrigerant gas piping must be insulated.

It is recommended that the outline drawings in theDimensional Data section be studied and dimensionsproperly noted and checked against the selectedinstallation site. By noting in advance which featuresare to be used, proper clearance allowances can bemade for installation and possible future service.


SSA-SVX06J-EN 11

IImmppoorrttaanntt:: When installing these units “free standing”with discharge grills and isolators, a topsupport with isolator should be added toprevent tipping. Support and isolator canbe attached to a wall or other appropriatestructure.

If adding external accessories to the unit,additional clearances must be consideredfor the overall space needed.

For installation of accessories available for this airhandler, follow the installation instructions that areshipped with each accessory.

ClearancesAllow the following minimum clearances forserviceability:

• Front and Back – 24 in (610 mm)

• Sides – 22 in (559 mm) for 5 - 10 ton units and 32 in(813 mm) for 12.5 - 25 ton units

InstallationHorizontal SuspensionIf the air handler will be suspended, use a suspensionmounting kit to isolate the unit from the structure. Thisis usually accomplished with spring or rubber isolators,which are offered as an accessory.

Mounting rods must be field supplied. Isolatorselection is dependent upon total unit weight includingaccessories — see “Weights,” p. 21 for approximateunit and accessory weights.

Align holes in the cabinet with structural supports andsecure suspension rods to the structure, then to the airhandler cabinet. If hole locations do not permit properalignment with existing structure, it may be necessaryto field fabricate cross members on existing structuralbeams.

NNoottee:: When other than bottom return is to be used,side panel removal for return duct installationmust be secured over the bottom opening.

LevelingThis air handler has a double sloped drain pan. In orderto assure proper drainage along the length of the drainpan, it is important to have the unit properly leveled. Besure the air handler is level.

Auxiliary Drain PanA field fabricated, auxiliary drain pan should beinstalled under the unit for all horizontal applicationsand when air handlers are installed above ceilings or inother locations where condensate overflow may causedamage.

This drain pan will eliminate any excess condensationthat may be due to extreme humidity or an obstructeddrain in the primary drain pan. Drain lines from thispan must be installed, but should not be connected tothe primary drain line from the unit. Isolate theauxiliary drain pan from both the air handler and thestructure.

Refrigerant PipingInstallation, brazing, leak testing and evacuation ofrefrigerant lines are covered in the installationinstructions that shipped with the outdoor unit. Readthe instructions before beginning installation ofrefrigerant lines.

Filter Replacement











Air handlers are shipped with throwaway filtersinstalled.

NNoottee:: 2'' Merv 13 filters are available for field installoption only.

To replace filters from the end of the unit, removelower access panel (either end) and slide old filters outand replace with new ones.

To replace from the front of the unit, remove one “L”shaped angle. Remove and replace filters and reinstall“L” shaped angle. See Figure 20, p. 26.

To convert from 1” filter to a 2” filter on units soequipped, remove lower access panels from both endsof the air handler. Remove screws and rotate the “L”shaped angles from both the top and bottom of the

filter track 180° to increase the width of the filteropening.

Figure 20. Filter location

FilterFrame

Duct ConnectionsThe supply and return ducts should be connected tothe unit with flame retardant duct connectors to reducevibration transmission. The return duct should be sizedto the same dimensions as the return inlet of the unit.

EDC Switch WiringThe Evaporator Defrost Control Switch is wired fromthe factory Normally Open to operate with Symbio™condensers. For operation with legacy Reliatel™ orElectromechanical condensers, change the wiring onthe switch to the Normally Closed position and connectthe wires from the switch to the wires from the legacycondenser that control this function.

Checkout ProcedureComplete the “Installation Checklist,” p. 29 onceinstallation of field wiring connections is complete. Alloperational checks (unit running) must be made afterthe outdoor unit is installed and systeminterconnection is complete.


SSA-SVX06J-EN 33

StartupHeating and Cooling SetpointArbitrationAll control function setpoints are set through one of theSymbio™ 700 user interfaces. If no changes are made,the controller will operate, as configured, based on thedefault settings. Refer to the Symbio 700 Controllerwith Odyssey Split Systems Application Guide fordetails about which setpoints are required perapplication.

Constant Volume Units(Unit model number digit 15 = "1")

Unit is shipped for nominal airflow with nominal staticpressure. Please refer to the fan performance table inthe product catalog and select the proper drive packagefor each application. Failure to do so could result inimproper airflow causing coil frosting or condensatemanagement problems. Condensate managementproblems such as water blow off could be the result oftoo great of air face velocity across the coil. To ensureproper operation refer to “Fan Belt Adjustment,” p. 46.

SZVAV and Two Speed Air-Handling Units with Symbio™™Condenser Units(Unit Model Number Digit 15 = “D”)

The Symbio 700 controller provides integrated SupplyFan speed setpoint control for paired air handler unitswith VFDs for SZVAV and Two Speed fan operation.These setpoints can be manipulated through theSymbio 700 user interface (including the SymbioService and Installation app) or through a connectedBAS if required.

Figure 29. Supply Fan speed setpoints

34 SSA-SVX06J-EN

Each setpoint operates as described below.

SSuuppppllyy FFaann MMaaxxiimmuumm SSppeeeedd SSeettppooiinntt ((RRaannggee:: 6677--110000%%,, DDeeffaauulltt:: 110000%%))

The Supply Fan Maximum Speed Setpoint correlates tothe maximum reference setting in the VFD (defaulted to60Hz from the factory). With the Supply Fan MaximumSpeed Setpoint at its default value of 100%, andparameter 6-15 in the VFD at its default value of 60Hz,the maximum VFD output will be 60Hz. If the userchooses to reduce the Supply Fan Maximum SpeedSetpoint, it will effectively reduce the maximum VFDoutput from its configured value. See the examplebelow:

EExxaammppllee::

Parameter 6-15 in the VFD = 60Hz

Supply Fan Maximum Speed Setpoint = 80%

Effective Supply Fan Maximum VFD Output = 80% x60Hz =48Hz

If the desired maximum operating point from thecatalog fan table is lower than 40Hz, parameter 6-15 onthe VFD must be reprogrammed to 50 Hz. The VFD ispreset from the factory to a default of 25 Hz for thelower limit and does not need to be reprogrammed.

SSuuppppllyy FFaann MMiinniimmuumm SSppeeeedd SSeettppooiinntt ((RRaannggee:: 00--110000%%,, DDeeffaauulltt:: 00%%))

The Supply Fan Minimum Speed Setpoint correlates tothe minimum reference setting in the VFD (25Hz fromthe factory). With the Supply Fan Minimum SpeedSetpoint at its default value of 0%, and parameter 6-14in the VFD at its default value of 25hz, the minimumVFD output will be 25Hz. If the user chooses to increasethe supply Fan Minimum Speed Setpoint, it willeffectively increase the minimum VFD output from itsconfigured value, up to the Effective Supply FanMaximum VFD Output as determined by the SupplyFan Maximum Speed Setpoint. See the example below:

EExxaammppllee::

Parameter 6-14 in the VFD = 25Hz

Effective Supply Fan Maximum VFD Output (based onSupply Fan Maximum Speed Setpoint) = 60Hz

Supply Fan Minimum Speed Setpoint = 50%

Effective Supply Fan Minimum VFD Output =

(Effective Supply Fan Maximum VFD Output – VFDParameter 6-14) x 50% + 25Hz = 42.5Hz

The fan belts must be inspected periodically to assureproper unit operation. Replacement is necessary if thebelts appear frayed or worn.

When removing or installing the new belts, do notstretch them over the sheaves. Loosen the belts usingthe belt tension adjustment bolts on the motormounting base.

Once the new belts are installed, using a Browning orGates tension gauge (or equivalent), adjust the belttension as follows:

1. To determine the appropriate belt deflection:

a. Measure the center-to-center shaft distance (ininches) between the fan and motor sheaves.

b. Divide the distance measured in Step 1a by 64;the resulting value represents the amount ofbelt deflection that corresponds to the properbelt tension.

2. Set the large O-ring on the belt tension gauge at the

deflection value determined in Step 1b.

3. Set the small O-ring at zero on the force scale of thegauge plunger.

4. Place the large end of the gauge at the center of thebelt span; then depress the gauge plunger until thelarge O-ring is even with the top of the next belt oreven with a straightedge placed across the fan andmotor sheaves.

5. Remove the belt tension gauge. The smallO-ring now indicates a number other than zero onthe plunger’s force scale. This number representsthe force (in pounds) required to give the neededdeflection.

6. Compare the “force” scale reading (Step 5) with theappropriate “force” value listed in the Belt tensiontable. If the “force” reading is outside the range,readjust the belt tension.

NNoottee:: Actual belt deflection “force” must notexceed the maximum “force” value shown inFigure 44, p. 46.

Recheck the belt tension at least twice during thefirst 2 to 3 days of operation. Belt tension maydecrease until the new belts are “run in”.

Conduct the following maintenance inspections onceper month:

☐ Inspect air filters and clean (or replace) if necessary.

☐ Check unit wiring to ensure all connections are tightand that the wiring insulation is intact.

☐ Check drain pans and condensate piping to insurethey are free of obstacles.

☐ Manually rotate the indoor fan to ensure properoperation.

☐ Inspect the evaporator coils for dirt and debris. Ifthe coils appear dirty, clean them.

☐ Observe indoor fan operation and correct anyunusual or excessive vibration. Clean blowerwheels as needed.

Annually (Cooling Season)The following maintenance procedures must beperformed at the beginning of each cooling season toensure efficient unit operation:

☐ Perform all of the monthly maintenanceinspections.

☐ With the unit operating, check unit superheat andrecord the reading in the “Maintenance Log,” p. 49

☐ Remove any accumulation of dust and/or dirt fromthe unit casing.

☐ Remove corrosion from any surface and repaint.Check the gasket around the control panel door toensure it fits correctly and is in good condition toprevent water leakage.

☐ Inspect the evaporator fan belt. If it is worn orfrayed, replace it.

☐ Inspect the control panel wiring to ensure that allconnections are tight and that the insulation isintact.

☐ Check refrigerant piping and fittings for leaks.

☐ Inspect the evaporator coils for dirt and debris. Ifthe coils appear dirty, clean them.

Coil CleaningRegular coil maintenance, including annual cleaning-enhances the unit's operating efficiency by minimizing:

• compressor head pressure and amperage draw• water carryover• fan brake horsepower• static pressure losses

At least once each year — or more often if the unit islocated in a “dirty” environment — clean the coil usingthe instructions outlined below. Be sure to follow theseinstructions as closely as possible to avoid damagingthe coils.
